PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 739,529, dated September 22, 1903.

Application filed Novemher 10, 1902. Serial No- 130,640. (No model.) I

To aZZ whom it may concern:

Be it known that I, JOHN S.:W00DBnInen, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Im: provement in Paper-Box Machines; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had 'to the accompanying drawings,

is fed in its passage to the. forming-dies.

which form a part of this specification.

My invention relates to an improvement inf paper-box machines, shown in the accompanying drawings and more particularly set forth for-operating the slitting-die E.

in the following specification and claims.

Referring to'the drawings, Figure 1 is a plan;

Fig. 2 is an end elevation. vFig. 3 is a cross-sectional view through. the receiving-pockets and showing-the same view of the machine.

supported in the channel iron or way provided for that purpose. Fig. 4,13 a perspective view of one of the segments containing the receiving pockets or dies. Fig. 5 is a plan view of a detail, showing parts in section, dis closing more particularly the means em ployedfor locking the receiving-pockets in position under the plunger and also the means for moving the receiving-pockets successively under said plunger. Fig. 6 is a cross-sectional view on the line a: a; of Fig. 5.

My invention contemplates a construction wherein a series of receiving pockets or dies are successively moved in position under the forming die or plunger to receive the newlyformed box, which is allowed toremain in the pocket until thoroughly dried, when it is discharged.

The particular feature of the invention consists in providing a closed channel in which the receiving-pockets travel for. the purpose of presenting a solid base, against which the forming-die forces the paper, thereby insuring the box having sharply-defined corners and squarely-formed side, and end walls. This is not possible where the paper is forced into a die open at the base. q

Another feature of the invention is the means employed for locking the receivingpockets under the forming-die and also the mechanism'employed to move the pockets successively into position.

Another feature of the invention is the manner. of constructing the forming die or plunger in two parts for the purpose of takingnpany wear that may occur in the plunger and to provide a minute adjustment of the parts. Y

Referring to the letters of reference shown on the drawings, A is the frame of the-machine, B'the main driving-shaft, and B the driving-pulley.

'O is one of the reels over which the paper D is a cam mounted on the driving-shaft for operating the gluing mechanism D.

E is a cam mounted on the driving-shaft F is a cam mounted on the driving-shaft for operating the cutting-off die, and G is a cam controlling the fingers G, designed to fold the ends of the side walls of the box. These fingers are thrust in and drawn out by the swinging arms G pivoted at g, the end of the upper arm G engaging the operating-cam G. These several parts are commonin machines ofethis class and need no further detail description, as they form no part of my invention.

, H is a cam or plunger T. p Iis a hand-wheel mounted on the drivingshaft and is designed to-provide means for operating the shaft when power is not applied to the Policy for the purpose of adjusting the parts by giving the driving mechanism a slight movement.

J is one of a pair of feed-rolls commonly employed to feed the ribbon of paper to the box-forming mechanism. One roll lies directly under: the other, and they are geared together by spur-gears, as shown at j, at one end of the shaft.

3' is a bevel-gear meshing with a similar gear on the shaft K, which is driven by sprocket connection K with the driving-shaft for operating the forming die 13. .On the shaft K is ane'ccentric L,designed to give a reciprocating movement to the bar L, which has an operating engagement with the swinging arm M, pivoted to the frame of the machine at m.

Zis a link connection between the bar L and that portion engaging the swinging arm M, providing a slight flexibility, necessary on account of the bar L havinga movement tangent to the are formed by the swinging of the arm M.

Z is a spring mounted on the rod engaging the link connection, and Z is a nut for adclosed base designed to receive the segments containing the pockets P.

R'is a knock-out plunger mounted in suitable hangers r,secured to the swinging arm M.

0" is apin engaged with the knock-out plungel, on which is provided a friction-roll 7".

R is a cam secured to the annular channel or way and is designed to force down the knock-out plunger when the operating-arm M, carrying the dog which engages the pockets, is moved forward by the rotation of the cam L. As the arm controlling the knockout plunger passes under the cam R the box contained in the pocket P registers with an opening (not shown) in the bottom of the channel-way Q and the box is thrown out.

Referring to Figs. 5 and 6 of the drawings, S is a bolt sleeved in the framework of the machine and provided at its outer end with an upstanding pin S. L is a cam or wedge secured to the bar L. p p are openings in the walls of the pockets P designed to receive the end of the bolt S to lock the pocket in position under the forming-plunger T. S is a spring engaging the end of the pin S, the tension of which is designed to draw the bolt into the opening 19 and the pin into operating contact with the wedge L Hare ways in which the forming-plunger T travels. This forming-plungeris made in two parts, the upper portion T engaging the operating-cam II, the parts T and T being connected together by a threaded-bolt connection adjusted by the nuts T The object of this adjustment, as has been heretofore suggested, is to provide means to take up the wear in the forming-die or to more accurately adjust the movement of the plunger with relation to the receiving-pockets.

It will be seen that when the cam L rotates and the bar L is carrying the wedge L it is thrust to the right, the wedge forcingthe locking-bolt out of engagement with the aperture in the pockets P, and when the arm L starts on its backward movement, due to the movement of the cam L, the swinging arm M, on which is mounted the dog N, will engage one of the pockets of the segments and move forward the series one point, or, in other words, the next successive pocket will be pushed into position under the forming-die, the adjustment of the several parts and the cam being so constructed as to bring about this result. When it has reached this position, the locking-bolt is again engaging the pocket and holding it in position until the forming-plunger T forces the paper down into the pocket and against the bottom wall of the channelway Q, It will be seen that the spring Z insures a suflicient latitude of adjustment, so that when the pockets are moved forward the bolt S will be in position to drop into place the moment the opening in the pocket is directly in line with the end of the locking-bolt.

The operation of the device will be readily understood. of a ribbon, is fed forward in the usual manner underthe several gluing, slitting, and cutting mechanisms (which form no part of this invention) into position under the forming-plunger T. The operation of the cam H then moves the plunger and forces the paper into the pocket designed to receive it. After the box is formed a further movement of the drivingshaft causes the cam L to rotate, thereby operating a connecting mechanism with the swinging arm M, on which the dog N is mounted, which serves to force forward the next succeeding pocket into position under theforming-die, when the operation just described is repeated. When the first box formed reaches the position directly over an opening provided in the bottom of the channel-way, a suitable knock-out plunger-as, for instance, that shown at R-is provided to discharge the boxes from the machine, the time intervening between the formation of the box and its discharge from the pocket being of sufficient duration to admit of the box being thoroughly dried.

While I have shown the pockets in segmental groups adapted to travel in a circular way, I would have it distinctly understood that I contemplate the employment of single pockets which may travel in a straight or circular way as coming within the scope of my invention, one of the essential features of which is the provision of a channel or way having a solid bottom against which the forming-die may operate.

Having thus described my invention, what I claim is 1. In a box-machine, the combination of a forming-plunger,a movable receiving-pocket, and a channel-way to guide the pocket to the plunger provided with a solid base below the plunger against which the plunger forces the paper in forming the box, substantially as described.

2. In a box-machine, the combination of a forming-plunger, a slidable receiving-pocket, and a channel-way to guide the pocket to the plunger provided with a solidbase below the plunger to support the paper-while the box is being formed, substantially as described.

3. In a box-machine, the combination of a forming-plunger, a plurality of receivingpockets grouped together, and a channel-way to guide the receiving-pockets to the plunger and provided with a solid base below the plunger to support the paper while the box is being formed, substantially as described.

The paper, which is in the form A pockets successively under the forming-plnnforming-plunger, a fixed 4. In a box-machine, the combination of a forming-plnnger,a fixed circular cbannehway having a solid base below the forming-plunger to support the paper while the box is being formed, and receiving-pockets adapted to travel in said channel-way, substantially as described. I

6. In a box-machine, the combination of a I channel-way having a closed base below the forming-plunger to support the paper while the box is being formed, receiving-pockets adapted to travel within said way, and means for moving said ger, substantially as described.

'7. In a box-machine, the combination of the forming-plunger, a channel-way, receivingpockets adapted to travel in said way, a horizontal swinging arm, one end being pivoted to the frame of the machine, an eccentric L,

means for connecting the eccentric with the swingingarm whereby the same may be 0perated, and a dog M mounted'on said swinging arm to engage the pockets and force them successively forward when the swinging arm is operated, substantially as described.

8. In a box-machine, mechanism for automaticallylocking and releasing the receivingpockets under the formin g-plunger consisting (of a sprlng-actnatedsliding bolt S adapted to engage the pockets successively, an arm provided with a wedge-shaped portion to engage said bolt, and an eccentric for operating said arm, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
